Mark Murphy argues that the property identity version of divine command theory, coupled with the doctrine that God has freedom in commanding, violates the supervenience of the moral on the nonmoral. In other words, they permit two situations exactly alike in nonmoral facts to differ in moral facts. I give three arguments to show that a divine command theorist of this sort can consistently affirm moral supervenience. Each argument contends that there are always nonmoral differences between worlds with different divine commands. If there are such nonmoral differences, then there’s no conflict between divine command theory and moral supervenience.

William Lane Craig offers two philosophical arguments for the conclusion that the universe began to exist. To be compelling, these arguments must not only be sound—we must also have reasons to believe that they are sound. I determine that these arguments do not provide such reasons to many individuals. The arguments ultimately rely on supposedly intuitively obvious absurdities. However, if one fails to see these ostensible absurdities—as many philosophers do—then for her, Craig’s arguments lack all epistemic force.

Adequate and inadequate ideas play a central role in Spinoza’s system. A number of recent commentators have suggested that the internality or externality of an idea’s immediate cause is a necessary and sufficient condition of the idea’s adequacy or inadequacy, respectively. I show that this thesis is subject to counterexample and briefly explore the significance of this critique for recent interpretations. I offer an alternative interpretation on which adequate and inadequate ideas are characterized by the manner in which they grasp their objects. Adequate ideas conceive of their objects as following from God. Inadequate ideas conceive of their objects as affecting the body at a time and place.

I argue that some of the most prominent interpretations of Reid's response to skepticism marginalize a crucial aspect of his thought: namely, that our common sense beliefs meet whatever normative standards of rationality the skeptic might fairly demand of them. This should be seen as supplementary to reliabilist or proper functionalist interpretations of Reid, which often ignore this half of the story. I also show how Reid defends the rationality of believing first principles by appealing to their naturalness and irresistibility. The resulting interpretation supplies Reid with a more satisfying and formidable response to the skeptic than interpretations currently offer.
